--------------------------------------

Hi Marek, 
Finally, figured out it's em.clear() that causing currentUser value lost. but I am wondering, even "currentUser" in the session has been detached, but why not calling @Factory getUser() method again to gain value again? Why just create a new empty User? 
Best regards, 
Anna
